Abstract: It is an objective of the present invention to provide a method for producing an air-permeable composite sheet which has excellent mechanical strength and compression resistance as well as PTFE's innate property such as air-permeability, water repellency, heat resistance and chemical resistance; and a filter and a fabrics material containing the air-permeable composite sheet produced by the method as a constituent material. The method for producing an air-permeable composite sheet according to the present invention is characterized in comprising steps of filling pores of a porous PTFE sheet with a hardenable material solution; hardening or semi-hardening the porous PTFE sheet filled with the hardenable material solution; and expanding the hardened or semi-hardened porous PTFE sheet.
